Sahih Bukhari Volume 8, Book 73, Hadith Number 24.

Narated By ‘Aisha : (The wife of the Prophet) A lady along with her two daughters came to me asking me (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and then she got up and went away. Then the Prophet came in and I informed him about this story. He said, “Whoever is in charge of (put to test by) these daughters and treats them generously, then they will act as a shield for him from the (Hell) Fire.”
